DUMP-CAR.

Specification of Letters Patent.

PatentedMay 8, 1906.

To all whom it may concern.-

Be it known that I, ELI S. HART, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvemerits in Dump-Cars, of which the following is a specification.

My invention relates to that class of dumpcars which are provided with a V-shaped' dumping-hopper bottom arranged longitudinally of the car and with its apex at or near the longitudinal center thereof, and especially to the means by which the dumping-doors are opened and closed, all of which will more fully hereinafter appear.

The principal object of the invention is to provide a simple, economical, and efficient V- shaped dumping-car formed of swinging sections with mechanism for operating the same.

The invention consists principally in a dumping-car in which there are combined a supporting-frame portion provided with a V- shaped dumping-bottom portion extending longitudinally of the car and having two swinging dumping-sections and mechanisms for operating such swinging sections independently, so that either or both of them may be opened and closed. The invention consists, further and finally,

in the features, combinations, and details of construction hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a plan sectional view of a portion of a car when constructed in accordance with these improvements looking at it from above and taken on line 1 of Fig. 4; Fig. 2 an enlarged cross-sectional view taken on line 2 of Fig. 1 looking in the direction of the arrow, both upper dumping-sections being lowered; Fig.

2, a similar view showing the upper dumpold as will properly disclose the invention to others and enable those skilled in the art to practice the same, leaving out of consideration other and well-known elements, which. if set forth herein, would only tend to confusion, prolixity, and ambiguity.

In constructing a car in accordance with these improvements I make a supportingframework formed of longitudinal sills a and b and cross and end sills c and d, secured together in any well-known or desired manner and preferably provided with a superstructure or upper framework of the ordinary stock-car type, having side walls e and end wallsf.

It is very desirable in the present state of the art that this type of car should not only be capable of being used as a stock-car to carry stock or cattle in one direction or at one season of the year and coal, coke, or similar bulky material during other seasons of the year. For thispurpose I provide a V'' shaped hopper portion extending longitudinally of the car with its apex at or near the longitudinal center thereof and formed of 3 two sets or sections, a lower set formed of two swinging dumping-doors g and g, pivotally secured to the framework of the car and extendin below the same, and an upper set formed 0 two swinging sections it and h, pivotally secured or fulcrumed on the framework of the car and extending above the same, so as to form the upper inclined side walls of the hopper when in one position, as shown at the top of Fig. 1, or a portion of the flat floor of the car when in a second position, as shown at the bottom of Fig. 1. This type of car is also preferably provlded with a plurality of movable end sections secured thereto, one set i pivotally secured at its upper edges to the superstructure of the car and forming, as shown in Fig. 4., a portion of the vertical end walls of the car when in one position and a portion of the inclined end walls of the hopper when in a second position, as shown in Fig. 3, and a second movable set of end sections 1', forming when in one osition a portion of the floor of the car, as s own in Fig. 4, and when in a second position a portion of the inclined end walls of the hopper, as shown in Fig. 3. Flaps j, forming triangular gusset-plates, are hinged to each end of 10 5 the swinging bottom sections h and h and sons or which can be used as an inclosed' dumping-car, such as a stock or dump car, which will dump all the material contained therein from end to end and from side to side thereof, all of which will be thoroughly understood and appreciated by those skilled in the When used as a dumping-car, it is very desirable that mechanism be provided and so constructed and arranged that one or both of the lower dumping-doors'of the V-shaped hopper .may be opened or closed Whenever desirable or necessary. With certain kinds of freight-such as small ballast, broken ore or rock, hard coal, and the like-it is only necessary to operate one dumping-dooras,

for instance, the section g; but when large bulky freight is carried, such as blocks of soft coal, &c., it is necessary in order to quickly discharge the same that both dumping-doors may be opened. For this purpose arock-shaft 7c is provided for each set or section of these lower portions of the hopper, one arranged at each side of the longitudinal center of the car and opposite the particular dumpingdoors or sections which it is to operate. Each of these rock-shafts is provided with a plurality of chain mechanisms Z, wound therearound and connected with the free edges of the swinging dumping-doors on the opposite side of the car. Idler-pulley mechanism m is also provided and rotatablli mounted in the framework of the car, so that .the chain mechanism is passed thereover in such'manner that the dumping-doors-may be operated without disturbing the relative positions of the chains-in otherwords, that the dumping-doors 9 may be operated without disturbing the chain mechanism which operates the dumping-door 9. Each of these chain mechanisms, which extend from one side of the car into the hopper-bottom, as shown at the right hand of Fig. 2 is provided with a hood p, which covers the same, as well as the idler-pulleys, so as to prevent the loose freight from contacting or disturbingthe same, all of which will be understood and appreciated by those skilled in the art. Each of the rock-shafts may be provided at one or both ends with lever mechanism 9, as shownto the left of Fig. 1, .for operating the same. When the movable end sections 9 are arranged at an incline, struts t, which are pivoted to the supporting-framework of the car, are raised to the position shown in Fig. 3

and act to support the same. These struts may be folded down, however, as shown in Fig. 4, when it is desired to use them.

I claim 1. In a dump-car of the class described, the combination of a supporting-frame portion, a V-shaped dumping-bottom portion extending longitudinally of the car and having two swinging dumping-sections movable into and out of engagement with each other, and mechanism for operating such dumping-sections independently so that either or both may be opened or closed, substantially as described.

2. In a dump-car of the class described, the combination of a supporting-frame portion, a V-shaped hopper extending longitudinally thereof with its apex arranged at or near the longitudinal center of the car and formed of two swinging dumping-sections, a rock-shaft and chain mechanism for each set of dumping-sections, and idler-pulleys over which the said chain mechanisms are passed, substantially as described. I
